DS1233MS-55/T&R

Supervisors Overview

The DS1233MS-55/T&R is a voltage supervisory circuit from the EconoReset series, designed for power-on reset and voltage monitoring applications. It features an active-low reset output with open drain or open collector configuration. The device monitors a single voltage input channel with a threshold of 4.625 V and an overvoltage threshold of 4.75 V. Key electrical parameters include a minimum reset timeout of 200 ms, a maximum operating supply voltage of 5.5 V, and a typical operating supply current of 50 uA. It is housed in an 8-SOIC package and operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides power-on reset functionality with a dedicated voltage monitoring channel
• Features an active-low reset signal with open drain or open collector output capability
• Includes power-fail detection to assist in data preservation during voltage drops

Supervisors Applications

• Power-on reset generation in embedded systems
• Voltage monitoring for microprocessors and memory devices
• Data protection circuits requiring power-fail signaling

Supervisors Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging when ordering. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure compatibility with the 8-SOIC footprint and check RoHS compliance status for your region. Cross-reference the exact part number DS1233MS-55+T&R with official distributor catalogs to confirm availability and lead times.

Supervisors Selection Notes

Select this component for applications requiring simple voltage supervision without manual reset or watchdog timer functions. The open drain/open collector output allows for flexible interfacing with various logic families. Consider the 50 uA supply current for low-power designs. Verify that the 4.625 V threshold aligns with the system's nominal voltage levels.

Supervisors Part Context

This part belongs to the DS1233M family of supervisory circuits by Maxim Integrated (now Analog Devices). These devices are designed for cost-sensitive applications needing basic reset and monitoring capabilities. The MS variant specifically denotes the 8-SOIC surface-mount package option, distinguishing it from through-hole alternatives like the TO-92 package found in other family members.

Supervisors Replacement Considerations

Check for direct substitutes within the DS1233 family such as DS1233MS-55 without the T&R suffix for different packaging. Verify pinout compatibility if considering alternative manufacturers' supervisors with similar thresholds and output types.
